Specification of Letters Patent.

Application filed May 14, 1909.

Patented Sept. 5, 1911. Serial No. 496,091.

To all whom it may concern:

Be it known that we, HENRY ELLIS HAR- RIs and ANNIE LOUISA HARRIs, 'bothsubjects of the King of Great Britain, and residing, respectively, at 64Finsbury Pavement, and 136 Mile End road, London, England, the jointexecutors of the last will and testament of ALFRED ELLIs HARRIS,deceased, as by reference to the duly-certified copy of letterstestamentary hereto annexed will more fully explain, are in possessionof new and useful Improvements in Gas-Burners, of which the said ALFREDELLIs HARRIS was the inventor and of which the following is aspecification.

This invention relates to atmospheric gas burners of the type whereinthe gas burns simultaneously from a series of apertures or nozzles andwhich are especially applicable for use in connection with water heatingapparatus, cooking appliances and the like, the object of the inventionbeing to provide for an even distribution of gas over the whole seriesof burner apertures or nozzles so as to provide as far as possible thatthe several flames or jets of gas shall be uniform. v

A burner constructed according to this invention comprises a series ofsuperposed pipes or sections connected to a common supply passage orconnected to each other by junction tubes (which may be staggered) thesaid supply passage or the burner pipes themselves being providedinternally with baffle plates which serve to break up the gas currentsso as to cause a thorough mixing of the gas and air and also to insurethat the proper supply of gas shall reach each burner hole or nozzle.

To enable the invention to be fully understood we will describe the sameby reference to the accompanying drawing, in which Figure 1 is anelevation of a burner having a series of superposed pipes connected to acommon supply pipe, and Fig. 2 is a vertical section on the line 2-2Fig. 1, and Fig. 3 is a horizontal section on the line 3-3 Fig. 1. Figs.4 and 5 are respectively a front elevation and a side elevation showingthe arrangement wherein the burner tubes are connected together, andFig. 6 is a horizontal section on the line 66 Fig. 4.

a, a indicate the burner tubes which are advantageously of a somewhatpear or oval shape in transverse section and b, b are the burneropenings formed therein, preferably on the underside. As shown in Figs.2 and 3 these tubes are all connected to a common supply pipe 0preferably of rectangular cross section, the said supply pipe beingconnected with the mixing chamber d in which the mixture of gas and airis supplied in the usual manner through the mixer e, is the bailie platewhich, in accordance with the invention, is inserted in the tube 0, thesaid baflle plate being of slightly less width than the tube 0 as seenat 0, 0 Fig. 3, and being of a zig-zag or sinuous shape so that wheninserted in the said tube the angles or corrugations will come intocontact with opposite walls of the chamber. WVith this arrangement itwill be understood that as the gas leaves the mixing chamber d and flowsupward through the channels at each side of the baffle plate, asufficient supply for each of the burner tubes flows into said tubes,and by reason of the contact of the baffle plate with the wall of thetube 0 above the openings into said burner tubes, issues through theburner apertures.

In the arrangement of the invention shown in Figs. 4 to 6 the severalburner tubes a, a are directly connected by junction tubes 9, g whichare staggered in order to place them out of alinement so that the gaswhich enters them in connection with the lower burner tubes shall notpass straight upward but be caused to travel in a zig-zag or sinuouscourse.

In order to further distribute the gas each of the burner tubes maycontain a sinuous or corrugated baflie plate f as shown in Fig. 6. Inthis modification the bafiie plate f is placed in the tubes at, so as todivide the upwardly flowing current of gas. The part of the current onthe side opposite the burner apertures will flow through the pipes 9above the same, into the next burner tube. The portion of the gasflowing upward on the side adjacent" to the burner openings, will fillthe space in the tube on that side of the baflle plate, forcing aportion out through the burner aperture, the remainder passing over thebattle plate and joining the directly upward flowing current, as thebattle plates are of less width than the tubes a. The corrugations inthe baffle plates f serve to force thegas flowing upward from the tube9, over said corrugations, toward the burner apertures. I

Having now particularly described and ascertained the nature of the saidinvention andin What manner the same is to be performed, We declare thatwhat e claim is I 1. An atmospheric gas burner, comprising a series ofsuperposed burner tubes having burner orifices, and means for conductinga gaseous burning mixture to said orifices in-.

gered junction tubes, and interior baflies in the burner tubes of lesswidth than said burner tubes and located over the inlet apertures ofsaid tubes.

3. In an atmospheric gas burner, the combination with a series ofsuperposed burner tubes, of connecting supply pipes and baflies thelatter being of zig-zag form within the burner tubes of less Width thanthe tubes, to divide the flow of gas which enters the burner tubes.
